DESCRIPTION

The DG2747, DG2748, and DG2749 are high performance,

low on-resistance analog switches of dual SPST

configuration.

Built on Vishay Siliconix's sub-micro CMOS technology, the

DG2747, DG2748, DG2749 achieve switch on-resistance of

0.4 Ω at 2.7 V V+ and 0.3 Ω at 4.3 V V+. It provides 0.1 Ω

flatness at 2.7 V V+, and total harmonic distortion to 0.03

(frequency range 20 Hz to 20 kHz). It achieves - 72 dB

off-isolation and - 100 dB crosstalk at 100 kHz. Its - 3 dB

bandwidth is up to 93 MHz.

It can switch signals with amplitudes of up to VCC to be

transmitted in either direction.

The select pins of the control logic can tolerate voltages

above V+. Logic high is 1.4 V to make it compatible with

many low voltage digital control circuits.

Combining wide operation voltage, low power, high speed,

low on-resistance and small physical size, the DG2747,

DG2748, DG2749 are ideal for portable and battery powered

applications requiring high performance and efficient use of

board space.

The DG2747, DG2748, DG2749 come in a small miniQFN-8

lead package (1.4 x 1.4 x 0.55 mm). As a committed partner

to the community and the environment, Vishay Siliconix

manufactures this product with the lead (Pb)-free device

terminations and is 100 RoHS compliant.
